Aviation safety reports, made easier to study
NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.
The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.
The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

THE PILOT STATED THAT DURING CRUISE FLIGHT THE LEFT ENGINE BEGAN TO RUN ROUGH AND THEN LOST POWER COMPLETELY. WHEN ATTEMPTS TO RESTART WERE UNSUCCESSFUL, HE FEATHERED THE PROPELLER AND TURNED TOWARDS THE NEAREST AIRPORT TO LAND. HE EXTENDED THE LANDING GEAR WHEN THE AIRPLANE WAS ABOUT ONE MILE FROM THE RUNWAY THRESHOLD, BUT DID NOT GET A GEAR DOWN AND LOCKED INDICATION. WITH ENGINE DRIVEN HYDRAULIC PRESSURE UNAVAILABLE FOR GEAR EXTENSION, EMERGENCY MANUAL GEAR EXTENSION IS REQUIRED. THE PILOT STATED HE DID NOT HAVE TIME FOR MANUAL GEAR EXTENSION, AND JUDGED A GO-AROUND TO BE INADVISABLE. HE SIDE-STEPPED AND LANDED ON THE SNOW-COVERED GROUND ADJACENT TO THE RUNWAY. THE PARTIALLY EXTENDED LANDING GEAR COLLAPSED UPON TOUCHDOWN AND THE AIRPLANE CAME TO A STOP NOSE DOWN IN THE SNOW. THE LOSS OF ENGINE POWER WAS DUE TO A FAILED VALVE IN THE NUMBER 3 CYLINDER.
NTSB Probable Cause
THE PILOT'S LACK OF FAMILIARITY WITH AIRCRAFT SYSTEMS WHICH RESULTED IN HIS FAILURE TO EXTEND THE LANDING GEAR BY THE ALTERNATE SYSTEM. A FACTOR WAS THE LOSS OF ENGINE POWER.
